Liquid Crystal Display Driver (S08LCDV1)
9.1
The LCD driver module is a CMOS charge pump voltage inverter that is designed for low-voltage,
low-power operation. The LCD driver module is designed to generate the appropriate waveforms to drive
multiplexed numeric, alpha-numeric, or custom LCD panels. Depending on LCD module hardware and
software configuration, the LCD panels can be either 3 V or 5 V and be driven by different waveform
modes. The LCD module also has several timing and control settings that can be software configured
depending on the applications requirements. Timing and control consists of registers and control logic for:
In a 64-pin package, the LCD module can be configured to drive 4 backplanes/32 frontplanes (128
segments) or 3 backplanes/33 frontplanes (99 segments). In a 80-pin package, the LCD module can be
configured to drive a maximum of 4 backplanes/40 frontplanes (160 segments) or 3 backplanes/41
frontplanes (123 segments). These configurations are summarized in
